LTST-T680UBWT

LED Indication - Discrete Overview

The LTST-T680UBWT is a single-color blue surface-mount LED manufactured by Lite-On Inc. It utilizes a PLCC2 (3528 metric) package with dimensions of 3.2 mm length, 2.8 mm width, and 1.9 mm height. The component emits light at a peak wavelength of 470 nm with a viewing angle of 120 degrees. Key electrical parameters include a forward current of 20 mA, a forward voltage of 3.4 V, and a power rating of 102 mW. The optical intensity is rated at 280 mcd. It features a water-clear, round flat lens and operates within a temperature range of -40°C to +85°C.

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to ensure the correct lens color and packaging configuration match project requirements. Confirm moisture sensitivity level handling procedures during storage and assembly. Check RoHS compliance status against current environmental regulations. Validate that the reel quantity aligns with production volume needs. Ensure the supplier provides official datasheets for final technical confirmation before purchase.

LED Indication - Discrete Selection Notes

Select this component when a standard blue SMD LED with a 3528 footprint is required. Consider the 3.4 V forward voltage drop for circuit design compatibility. Evaluate the 280 mcd intensity against visibility requirements for the intended application environment. Verify that the operating temperature range meets the system's thermal constraints. Compare the physical dimensions against available PCB space to ensure proper fitment.

LED Indication - Discrete Part Context

The LTST-T680UBWT belongs to the LTST-T680 series of single-color LEDs from Lite-On Inc. This series offers various color options including red, green, yellow, and blue within the same PLCC2 package form factor.
